Abstract
A multi-homed edge device VxLAN data traffic forwarding system includes a first VTEP device that receives an Ethernet packet from a first edge device, encapsulates the Ethernet packet in a VxLAN packet, generates a source port value, and provides the source port value in a field in the VxLAN packet. The first VTEP device transmits multiple copies of the VxLAN packet to second VTEP devices that each determine whether the source port value in their respective copy of the VxLAN packet is included in a forwarding range for that second VTEP device that is different than forwarding range(s) for each of the other second VTEP device(s). If not, that second VTEP device prevents information in that copy of the VxLAN packet from being transmitted to the second edge device. If so, that second VTEP device transmits information in that copy of the VxLAN packet to the second edge device.
